PORTAL MULTI-LINGUAL AND CHANGE LANGUAGE PROBLEM

Question

I need to implement language change in portal. I can't use the standard Set Language portlet, because my language change mechanism should involve redirection to an other portal page. Is there any API I can use to implement language change behavior? (Example code would be greately appreciated.)
In some cases I need to force the language of some specific portal pages, regardless of the current language setting of the portal. Is there any way to achieve that? I've experience with the default language setting of the page groups, but I've found that the portal ranks this setting below the current language setting of the portal and the "Accept-Language" header of the browser request. I've been thinking of hacks like a servlet filter or an apache mod tricking with the headers (Accept-Language) and cookies (NLS_LANGUAGE) of the browser request, but that's not so clean. So do I have any options to force the language?

Answer 1

I think it's this answer comes late for you, but If anyone it's interested, we use (in version 10.1.4) this function:
PORTAL.wwctx_app_language.set_language(p_http_language => 'es-es',
                                                       p_nls_language => PORTAL.wwnls_api.SPANISH,
                                                       p_nls_territory => PORTAL.wwnls_api.TER_SPAIN,
                                                       p_requested_url => url);
Where 'url' is the url you want to come back.
Remember you can call any function/procedure by the url: /portal/pls/porta/squema.name_of_the_proc, where you have to substitute squema and name_of_the_proc by tyhe ones you need to call (don't forget privileges).
Good luck
